Dry skin is a skin type: skin that naturally produces too little sebum. Dehydrated skin is a skin condition: moisture deficiency in the skin itself, which can occur in any skin type, including oily skin. The problem is that many people do not realize this and treat their dehydrated skin with heavy creams, while the issue actually lies in continuous moisture loss. Without intervention, the skin remains stuck in a vicious cycle: moisture flows from the deeper skin layers to the outside and evaporates into the air.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eDermalogica Circular Hydration Serum is developed to break exactly this cycle. The formula combines enhanced hyaluronic acid, polyglutamic acid from fermented soy, and an algae complex that addresses moisture on three different levels simultaneously: immediate hydration, replenishing moisture reserves, and preventing future evaporation. Clinical tests show that 97% of users experience more hydration after 20 minutes and 87% still after 10 hours. The 30ml size is the standard size and good for about three months of daily use.\u003c\/p\u003e\n\u003ch2 class=\"text-text-100 mt-3 -mb-1 text-[1.375rem] font-bold\"\u003eBenefits\u003c\/h2\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eBreaks the cycle of continuous moisture loss in dehydrated skin\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eHydrates immediately and long-lastingly, clinically proven up to 10 hours after application\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eReplenishes the skin's natural moisture reserve thanks to polyglutamic acid\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eBalances the skin microbiome with a postbiotic oat complex\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eLight gel texture suitable for layering under makeup or moisturizer\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 class=\"text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold\"\u003eActive ingredients\u003c\/h3\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eEnhanced hyaluronic acid (Hyaluronic Acid \u0026amp; Sodium Hyaluronate):\u003c\/strong\u003e The formula contains two forms of hyaluronic acid with different molecular weights. The larger hyaluronic acid forms a hydrating film on the skin surface and immediately smooths fine lines. The smaller sodium hyaluronate penetrates the upper skin layers and binds moisture where it is needed. Together, they ensure that hyaluronic acid works both immediately and sustainably.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003ePolyglutamic acid from fermented soy:\u003c\/strong\u003e A biotechnological ingredient that binds up to four times more moisture than hyaluronic acid, thereby strengthening the skin's natural moisture reserve. Unlike hyaluronic acid, which mainly works on the surface, polyglutamic acid forms a network in the skin that retains moisture for a long time. This is the ingredient responsible for lasting hydration up to 10 hours after application.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eAlgae complex (Laminaria Digitata, Chondrus Crispus, Gigartina Stellata, Macrocystis Pyrifera \u0026amp; Lithothamnion Calcareum):\u003c\/strong\u003e Five different algae extracts that together form a hydrating matrix. Each algae provides its own combination of minerals, amino acids, and polysaccharides that hydrate and nourish the skin. Brown algae and kelp mainly supply minerals, while red algae contribute polysaccharides that retain moisture in the skin.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eXylitylglucoside (plant-based sugar):\u003c\/strong\u003e A sugar molecule derived from plants that acts as a natural moisture magnet. It binds water molecules to the skin surface and helps prevent moisture evaporation. This is the third layer in the serum’s \"circular\" action: after hydrating and filling, this step prevents the moisture from escaping again.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003ePostbiotic complex (Lactobacillus Ferment \u0026amp; Avena Sativa):\u003c\/strong\u003e A combination of fermented lactic acid bacteria and oat extract that supports the natural skin microbiome. A healthy microbiome is essential for a well-functioning skin barrier, which in turn retains moisture better. With daily use, this ingredient builds a more resilient skin that dries out less quickly.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eAmino acid complex:\u003c\/strong\u003e A blend of amino acids similar to those naturally found in the skin. These substances are part of the skin’s natural moisturizing factor (NMF), which is often insufficient in dehydrated skin. By supplementing these amino acids externally, the skin’s natural moisture balance is literally restored.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003ePanthenol (provitamin B5) \u0026amp; Lactic Acid:\u003c\/strong\u003e Panthenol soothes and hydrates simultaneously, helping to restore the skin barrier. A low concentration of lactic acid gently supports natural skin renewal and ensures the skin better absorbs the other active ingredients.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eGlycerin, propanediol \u0026amp; butylene glycol:\u003c\/strong\u003e Three humectants that form the base of the formula and bind moisture from the surrounding air. Together they create the carrier system in which the high-tech ingredients can work optimally.\u003c\/p\u003e\n\u003ch3 class=\"text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold\"\u003eHow to use\u003c\/h3\u003e\n\u003col class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-decimal flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eThoroughly cleanse the skin in your morning and evening routine\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eOptionally apply your toner and let it fully absorb\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eDispense 4 to 6 drops of Circular Hydration Serum onto the palm of your hand\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eGently apply over face and neck with upward movements\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eFollow with your moisturizer and in the morning with an SPF of at least 30\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003ch3 class=\"text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold\"\u003eSuitable for\u003c\/h3\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eAll skin types, from dry to oily and combination skin\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eDehydrated skin that feels tight or looks dull\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eAdult and mature skin with fine lines due to moisture deficiency\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eSkin in dry climates, heated or air-conditioned environments\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eDaily use in both morning and evening routines\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 class=\"text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold\"\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cem\u003eHow long does the 30ml bottle last approximately?\u003c\/em\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eWith twice-daily use of 4 to 6 drops each time, a 30ml bottle lasts about three months. The light gel texture spreads easily, so you need only a small amount per application. With once-daily use, the bottle lasts twice as long.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cem\u003eWhat is the difference compared to a regular hyaluronic acid serum?\u003c\/em\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eMost hyaluronic acid serums work only superficially and for a few hours. Circular Hydration Serum combines hyaluronic acid with polyglutamic acid, an algae matrix, and plant sugars that together cover the full hydration cycle. Clinical tests show that 87% of users still experience increased hydration after 10 hours, which is not achievable with classic hyaluronic acid alone.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cem\u003eCan I combine this serum with retinol or vitamin C?\u003c\/em\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eYes. Circular Hydration Serum actually forms an excellent base for routines with active ingredients that stress the skin barrier. First apply Circular Hydration Serum, let it absorb, and then follow with your retinol or vitamin C. The hydration helps improve the skin’s tolerance for these actives.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cem\u003eDoes the hyaluronic acid feel sticky?\u003c\/em\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eNo. The formula is deliberately developed as a light gel texture that absorbs without a sticky residue. This makes the serum suitable to wear under makeup or as a layer in a more extensive routine without products pilling.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cem\u003eDoes this serum also work for oily skin?\u003c\/em\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eYes, and often surprisingly well for oily skin. Many people with oily skin also have dehydrated skin: the skin produces extra sebum to compensate for the lack of moisture. By providing moisture without adding lipids, sebum production often decreases rather than increases.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cem\u003eWhen will I see the first results?\u003c\/em\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eImmediately after application, the skin already feels fuller and more hydrated. Clinical tests show that 97% of users experience increased hydration after 20 minutes. For structural results, such as fewer fine lines and a less dull-looking skin, consistent use over four to six weeks is necessary.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cem\u003eCan I use this during pregnancy or breastfeeding?\u003c\/em\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe formula contains no retinoids or high concentrations of acids that should be avoided during this period. However, it does include essential oils such as bergamot, grapefruit, and sandalwood. If in doubt or if you have sensitive skin during pregnancy, we recommend briefly consulting your midwife.\u003c\/p\u003e","brand":"Dermalogica","offers":[{"title":"Default Title","offer_id":56635735277899,"sku":null,"price":75.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1009\/6908\/7307\/files\/a32d09c4c3d01c55ec8e0776a15b77feb1cf0413.jpg?v=1779226644","url":"https:\/\/webshop.glamskin.nl\/en\/products\/dermalogica-circular-hydration-serum-30ml","provider":"Glam Skin Webshop","version":"1.0","type":"link"}
